T at whom it may con/cerium Be it known that I, S END IVIARTIN MEYER, acitizen of the United States, and a resident of Brooklyn, New York, haveinvented a new, and useful Improvement in Devices for Light-: in g Lampsby Electricity,'of which the fol lowing is a specification.

In tlieaccompanying drawings, Figure 1 is an elevation, partly insection, of an oillamp and attachments embodying my invention. Figs.2,3,and 4 are detail views, hereinafter more particularly referred 'to.Figs. 5 and 6 are vertical sections of portions of the burner. Figs. 7and 11 are detail hori zontal sections of the same. Fig. 8 is a bottomView of the burner. Figs. 9 and 10 are detail vertical sections. Fig. 12is a detail elevation showing a modification hereinafter described. Fig.13 is a plan of thesame.

Referring to Fig. 1, 1 represents the body of the lamp; 2, the. base; 3,the burner; 41., the wick, and 5 the chimney.

, the said lever works in contact with a doublyinclined track 13, formedof spring-wire, the shape of which produces pressure uponthe lever as itapproaches its mid-stroke and causes it to be thrown to the end of itsstroke in either direction by the resilience of the spring. Thebatteries 19 and 20Yare removably mounted in the base 2 of the lamp bymeans of a clip 28 and the bearing 30, formed at its ends with pins orsockets, one of which engages with a stud or a socket 31,,while theother is caught by a pin or aperture, as the case may be, near the endof an elastic arm 33, secured within the base of the lamp. The battery19 is connected at 21 with the shell of the lamp and connected by wire22 with the battery 20 and this by the wire 23 with the induction-eoil24:, connected by an insulated wire 18 with a hinged arm 17, engaging ina clip 16, which is connected to an. insu lated spring-arm 15, bearingupon the verti- Fig. l" is a bottom view'of'the same.

8 represents the fixed sparking point, formed of an anguthe said hingedarm 17 and in dotted lines a flexible wire 17 which may be substitutedfor the hinged arm, as illustrated in Fig. 4:, where 17 represents aterminal socket in the said flexible wire fitting overapin 16, mountedin the lamp-burnem'in lieu of the clip 16 and in like manner connectedby the insulated spring-arm 15 with'the vibrating sparking point 10.

In the modification shown in Figs. 6 to 9 the conductor 18 is fixed inthe frame or lampbody 1 and when the burner 3 is placed in positionconnects with. an insulated ring 14: in the burner, as shown in .Fig. 9,electrically connected, through the spring 14:, with the verticalrock-shaft .or vibratingrod 9, which carries the vibrating sparkingpoint 10 and is vibrated by the hand-lever 12. Where either of the formsof connection illustrated in Figs. 2, 3, 4, and 5 are used, the

rock-shaft 9 is insulated from the burner by being stepped in aninsulated socket-piece 11, as shown in Fig. 5. In this instance the vertical rock-shaft 9 is electrically connected with the clip or socket 16through the spring 15.

In the modification shown inFigs. 10 and 11, the vertical rock-shaft isprovided with a fiat or squared portion 9*, against which'latter thespring 15 rests, so as to serve also to carry the rock-shaft to its fullstroke.

In the modification shown in Fig. 12 inclined plates 13 are provided asa substitute for the spring 13 to insure the complete stroke of thevibrating sparking point 10. The plates 13 are insulated by plates 13 ofmica or other material, to prevent electrical conductions when thevibrating sparking point 10 comes in contact with them. In vibrating thesparking point 10 in either direction it rides over one of the plates 13which deflects it upward as it approaches the fixed sparking point 8 andengages with the protuberant end thereof, from which it escapes with asudden movement and is received by the other inclined insulated plate13, so as to carry it to locate the spark in proximity to the lampwick.Furthermore, where both members have any considerable degree offlexibility or mobility they must overlap to such an extent in engagingthat the excessive length of the actuated member endangers tearing thewick.

Having described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. The combination of a lamp-body containing a suitable source ofelectricity, a burner removably mounted thereon, a conductor separablyconnecting the source of electricity in the body with a fixed conductorin the removable burner, connected with lighting device adjacent to thelamp-wick, a vibrating contact a making device on the burner closing thecircuit at mid-stroke only and automatically thrown to either extremityof its movement when moved by hand from the opposite extremity, to closethe circuit as described.

2. In a device for lighting oil-lamps by electricity, the combination ofa lamp-body 1, a burner 3 removably mounted thereon, asuitable source ofelectricity in the body of the lamp, a fixed sparking point 8 adjacentto the lamp-wick, a vertical rock-shaft 9, a contactspring 11 carried bysaid rock-shaft and engaging with the sparking point 8, a horizontal arm12 for rotating the rock-shaft 9, a spring device throwing therock-shaft to the extrem-- ity of its movement when moved to mid-strokefrom either direction, and separable conductors from the respectivepoles of the source of electricity to the connections of the spark-- ingpoints 8 and 10, permitting the removal of the burner from the body ofthe lamp in which the source of electricity is mounted, substantially asdescribed.

' 3. In a device for lighting oil-lamps by electricity, the combinationof a lamp-body containing asuitable source of electricity; a1ampburnerremovably mounted thereon, the contact-piece 8, inclined insulatingbearing-surfaces 13 adjacent thereto, a vibrating contact-spring 10sliding upon the bearing-surfaces 13 and engaging with the fixed point8, and separable conductors connecting the respective poles of thesource of electricity with the contact-points 8 and 10, substan= tiallyas described.

4;. In a device for lighting oil-lamps by electricity, the combinationof a lamp-body 1, containing a suitable source of electricity, a burner3 removably mounted thereon, a fixed contact-point 8 adjacent to thewick, a vibrat ing contact-spring 1O engaging with the contact-point 8at mid-stroke, inclined insulated bearing-surfaces 13 on either side ofthe contact-point 8 arranged to deflect the vibrating contact-spring 10as it is moved toward the contact point 8 from either direction andthrow it to the opposite extremity of its stroke, means for impartingvibratory movement to the spring 10 and separable conductors conmeetingthe respective poles of the source of electricity with the contactdevices 8 and 10, and permitting removal of the burner from the body ofthe lamp, substantially as described.
